How To Remove Oil-Based Paint from Plastic Using Warm Water and Dish Soap
Removing oil-based paint can be a challenging task, but with the right approach, warm water and dish soap can be effective in breaking down and removing the paint especially if the paint hasn’t cured.
Here’s a step-by-step guide to help you through the process:
Supplies You Will Need
- Warm water
- Dish soap (preferably one with degreasing properties)
- Clean, soft cloth or sponge
- Plastic scraper or putty knife
- Bucket or basin
Preparing the cleaning solution
Fill a bucket or basin with warm water. Mix a few drops of dish soap well to create a soapy solution.
The warm water helps to soften the paint, while the dish soap aids in breaking down the oils in the paint.
Soak the cloth or sponge
Dip a clean cloth or sponge into the soapy solution, allowing it to absorb the mixture. Squeeze out any excess water, leaving it damp but not dripping.
Apply the soapy solution
Gently rub the damp cloth or sponge onto the painted surface, focusing on the areas with oil-based paint.
Apply light pressure and use circular motions to help loosen the paint.
Let the solution sit
Once you’ve applied the soapy solution, allow it to sit on the surface for 5 to 10 minutes. This will give the soap time to penetrate and break down the paint.
Scrub and remove the paint
After letting the solution sit, take the plastic scraper or putty knife and gently scrape off the loosened paint. Be careful not to apply excessive force, which could damage the underlying surface.
Continue scrubbing and scraping until you’ve removed as much paint as possible.
Rinse the area
Once you’ve removed the paint, rinse the area thoroughly with clean water to remove any soap residue. This will also help you inspect if there are any remaining traces of paint.
Repeat if necessary
Depending on the amount and stubbornness of the paint, you may need to repeat the process multiple times to remove it completely.
Be patient and persistent, but avoid excessive scrubbing to prevent damage.
Clean and dry the surface
After removing the paint, clean the surface with a mild household cleaner or a mixture of vinegar and water to remove any remaining residue.
Finally, dry the area thoroughly with a clean towel or allow it to air dry.
Note: This method only works for wet or recent paint.
How to Remove Oil-Based Paint from Plastic Using Vegetable Oil
While vegetable oil may not be as effective as traditional paint removers, it can still remove oil-based paint from surfaces.

For stubborn or thick layers of paint, you may need to repeat the process several times to remove the paint fully.
Apply more vegetable oil and let it sit for a few minutes before scraping off the loosened paint.
Clean the surface
Once you have removed the paint, mix a small amount of mild dish soap with warm water in a bucket.
Dip a clean cloth or sponge into the soapy water and gently clean the area to remove any residual oil and paint residue.
Rinse the cloth or sponge frequently and change the water if it becomes dirty.
Dry and inspect the surface
After cleaning, use a clean cloth to dry the surface thoroughly.
Inspect the area to ensure all the paint has been removed. If any paint remains, you may need to repeat the process or consider using a different method or paint remover.
NOTE: Remember, vegetable oil may not be as effective as dedicated paint removers, so its success may vary depending on the type and age of the paint. You may want to consider Acetone if the vegetable oil method doesn’t yield satisfactory results.

How to Remove Oil-Based Paint from Plastic by Scraping it off
Using a paint scraper presents a speedy and uncomplicated method to eliminate spray paint, acrylic paints, and oil-based paints from plastic surfaces.
Supplies You Will Need
- Rubbing alcohol (isopropyl alcohol)
- Clean cloth or sponge
- Plastic Paint scraper or old credit card
- Gloves (optional)
- Put on gloves to protect your hands from rubbing alcohol and paint. This step is optional but recommended, especially if you have sensitive skin or are working with a large area.
- Moisten a clean cloth or sponge with rubbing alcohol. Make sure the cloth or sponge is damp but not dripping wet. You can pour some rubbing alcohol onto the cloth or sponge or soak it in a small container of rubbing alcohol.
- Gently apply the rubbing alcohol to the painted area on the plastic. Use the damp cloth or sponge to rub the surface in a circular motion. This helps to distribute the rubbing alcohol evenly and allows it to penetrate the paint.
- Rubbing alcohol acts as a solvent and helps break down the chemical bonds in oil-based paint, making it easier to remove. The alcohol dissolves the paint, softening it and loosening its grip on the plastic surface.
- Allow the rubbing alcohol to sit on the paint for a few minutes. This “dwell time” gives the alcohol more opportunity to dissolve the paint and make it more malleable for removal.
- Take the plastic paint scraper or old credit card and carefully scrape off the softened paint. Start from one edge of the painted area and work towards the center. Hold the scraper at a shallow angle to avoid scratching or damaging the plastic surface.
- Apply gentle pressure while scraping to remove the paint. If the paint resists, apply more rubbing alcohol to the area and allow it to sit for a few additional minutes before scraping again.
- For stubborn areas, you may need to repeat the process by reapplying rubbing alcohol and allowing it to sit for a few minutes before scraping again. Multiple rounds of application and scraping might be necessary to remove all the paint completely.
- When scraping, remove the paint and not simply smear it around. Wipe off the scraper or credit card with a cloth or paper towel periodically to remove any paint buildup.
- Once the paint is successfully removed, use a clean cloth or sponge soaked in rubbing alcohol to wipe the plastic surface. This step helps to remove any remaining paint residue or traces.
- Rubbing alcohol evaporates quickly, leaving minimal residue behind. However, it’s a good practice to rinse the plastic surface with water after using rubbing alcohol to ensure that all the alcohol and paint particles are thoroughly removed.
- If the plastic surface is heavily textured or has intricate details, you can use a toothbrush, a soft-bristled brush, and rubbing alcohol to scrub the paint away. Dip the brush in rubbing alcohol and gently scrub the painted area until the paint loosens and can be scraped off.
- Test the rubbing alcohol on a small, inconspicuous area of the plastic before applying it to the painted area. This helps you determine if the rubbing alcohol may cause any damage or discoloration to the plastic.
- Ensure you work in a well-ventilated area using rubbing alcohol, as its fumes can be strong. Avoiding direct contact with your eyes and ingestion is also a good idea. Keep the rubbing alcohol away from open flames or sparks, as it is flammable.
- If rubbing alcohol doesn’t work or causes adverse effects on the plastic, you can try alternative methods, such as using a paint remover specifically formulated for plastics. These products are designed to be safe on plastic surfaces and effectively remove oil-based paint.
Can You Use Paint Thinner With Oil-Based Paints?
Yes, paint thinner can be used to remove oil-based paints. Paint thinner is a solvent that helps break down and dissolve oil-based paint, making it easier to remove.
When using paint thinner, it is important to follow proper safety precautions, such as working in a well-ventilated area and wearing appropriate protective gear, including gloves and eye protection.
To remove oil-based paint with paint thinner, follow these steps:
- Ensure you are working in a well-ventilated area. Open windows or use fans to improve airflow.
- Put on gloves and eye protection to protect your skin and eyes.
- Dip a clean cloth or sponge into the paint thinner.
- Gently rub the cloth or sponge over the painted surface, applying moderate pressure. The paint thinner will start dissolving the oil-based paint.
- Continue rubbing until the paint begins to soften and lift off the surface.
- Use a scraper or putty knife to scrape away the loosened paint carefully. Be cautious not to damage the underlying surface.
- Repeat the process as needed until the paint is fully removed.
- Once the paint is removed, clean the surface with soap and water to remove any residue from the thinner.
Remember to dispose of the paint thinner and any paint waste according to local regulations.
Be aware that paint thinner is unsuitable for all surfaces, so it’s important to test it in an inconspicuous area before using it on the entire painted surface.
